Answer:
B and D
Step-by-step explanation:
5% of 35 can be represented as 5% [tex]\cdot35[/tex].
To find equations that make this work, we need to find different ways to represent 5%.
5% can be represented as fraction - over 100. The percentage over 100 will be equal to the percent.
So, [tex]\frac{5}{100}[/tex]. Multiplying by 35 gets us [tex]\frac{5}{100}\cdot35[/tex]
This means that Choice B is correct.
Another way to represent 5% is as a decimal.
We already know that the fraction form of 5% is [tex]\frac{5}{100}[/tex]. This means that in the decimal, the number 5 will be two place values to the right of the decimal place.
0.05
So the decimal expansion of 5% is 0.05. Multiplyin by 35 get us [tex]0.05\cdot35[/tex], so choice D works too.
Hope this helped!
Answer:
The answer is option D and BStep-by-step explanation:
To find the the value of the percentage of a number divide the percentage by 100 and multiply it by the number
So we have
5 percent of 35 is written as
[tex] \frac{5}{100} \times 35 \\ = \frac{1}{20} \times 35 \\ = \frac{7}{4} [/tex]
We have the answer as
1.75
From the options the one that has the same value as the above answer are
0.05 × 35 and 5/100 × 35

12. How does the sum of the exterior angles of a square compare to the sum of the exterior angles of a pentagon?
A The sum of the exterior angles of a square is greater.
B The sum of the exterior angles of a pentagon is greater.
C The two sums are equal.
D There is not enough information to compare the two sums.
Answer:
Option C.
The two sums are equal.
Step-by-step explanation:
In geometry, the sum of the exterior angles of any polygon will always give 360 degrees. This is regardless of the type of polygon, whether it is a triangle, quadrilateral, pentagon, or a decagon.
This means that the sum of the exterior angles of a square is equal to that of the pentagon.
As the number of sides that they have increases, the sizes of their internal angles get smaller, making the sum of their external angles remain at 360 degrees

Answer:
The other endpoint is ( -1,15)
Step-by-step explanation:
21.
The x coordinate of the midpoint is the sum of the x coordinate of the endpoints divided by 2
(-5 +x)/2 = -3
Multiply each side by 2
-5+x = -6
Add 5 to each side
-5+x+5 = -6+5
x = -1
The y coordinate of the midpoint is the sum of the y coordinate of the endpoints divided by 2
(-1 +y)/2 = -8
Multiply each side by 2
-1+y = -16
Add 1 to each side
-1+y+1 = -16+1
y = -15
The other endpoint is ( -1,15)

Answer: 50 Minutes = 309 gal
Step-by-step explanation: Every 10 minutes the amount of water goes up by 18, so after 50 minutes the water would be equivalent to 309 gallons.
Answer:
[tex]y=1.8x+219[/tex]
309 gallons
Step-by-step explanation:
So to find the linear equation, we can use the data from the table.
First, use the data from the table to find the slope. Pick any two points. I'm going to use (10,237) and (20,255).
Let (10,237) be x₁ and y₁ and let (20,255) be x₂ and y₂.
The formula for slope is given by:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Substitute:
[tex]m=\frac{255-237}{20-10}[/tex]
Simplify:
[tex]m=18/10=1.8[/tex]
Thus, the slope is 1.8. This means that 1.8 gallons of water flow into the tank every minute.
Now, let's find the slope-intercept. To do this, we can use the point-slope form. The point-slope form is:
[tex]y-y_1=m(x-x_1)[/tex]
Let's use (10,237) for consistency. Plug in 237 for y₁ and 10 for x₁. Also use 1.8 for m. Thus:
[tex]y-237=1.8(x-10)[/tex]
Distribute:
[tex]y-237=1.8x-18[/tex]
Add 237 to both sides:
[tex]y=1.8x+219[/tex]
What this means is that there is initially 219 gallons of water in the tank already. Every minute, 1.8 gallons is added further.
And that's our linear equation :)
So, to find the amount of gallons after 50 minutes, plug in 50 for x and solve:
[tex]y=1.8(50)+219\\y=90+219=309[/tex]
After 50 minutes, there will be 309 gallons of water.

Expand (a+b)3 in descending powers of a
==================================================
Explanation:
The coefficients of each term, from left to right are 1, 3, 3, 1
These coefficient values are found in Pascal's triangle in the third row.
The variable terms will have variable terms in the form a^m*b^n. To start off, m = 3 and n = 0 to get a^3*b^0 = a^3*1 = a^3. From there you will have m count down (3,2,1,0) and n will count up (0,1,2,3)
So for the second term we have m = 2 and n = 1 to get the variable term a^2*b^1 = a^2b
The third term has m = 1 and n = 2 to get the variable term a^1*b^2 = ab^2
Finally the last term has m = 0 and n = 3 to get a^0*b^3 = 1*b^3 = b^3
Those variable terms are them multiplied with the coefficients mentioned previously to get the final answer.
--------------------------
Another way you can do this problem is to use the distributive property and FOIL rule
(a+b)^3 = (a+b)(a+b)^2
(a+b)^3 = (a+b)(a^2+2ab+b^2) .... FOIL rule
(a+b)^3 = a(a^2+2ab+b^2) + b(a^2+2ab+b^2) ... distribute
(a+b)^3 = a*a^2+a*2ab+a*b^2 + b*a^2+b*2ab+b*b^2 ... distribute again
(a+b)^3 = a^3 + 2a^2b + ab^2 + a^2b + 2ab^2 + b^3
(a+b)^3 = a^3 + 3a^2b + 3ab^2 + b^3

What is the slope m of a line that is perpendicular to the line represented by x = 8? (If an answer is undefined, enter UNDEFINED.)
Answer:
slope = 0
Step-by-step explanation:
x = 8 is a vertical line parallel to the y- axis
A line perpendicular to it is a horizontal line parallel to the x- axis.
The x- axis has a slope of zero thus the line perpendicular to x = 8 is zero
The slope of a line is simply the ratio of a change in the vertical axis to the horizontal axis. The line perpendicular to [tex]x = 8[/tex] has a slope of 0
Given that
[tex]x = 8[/tex]
See attachment for the line of [tex]x = 8[/tex]
First, we determine the slope of [tex]x = 8[/tex]
The slope of a line (m) is calculated as:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]x = 8[/tex] means that, the value of x is always 8; irrespective of the y-value.
So:
[tex]x_2 = x_1 = 8[/tex]
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex] becomes
[tex]m = \frac{y_2 - y_1}{8-8}[/tex]
[tex]m = \frac{y_2 - y_1}{0}[/tex]
Assume the slope of the line perpendicular to [tex]x = 8[/tex] is [tex]m_2[/tex].
[tex]m_2[/tex] is calculated as follows:
[tex]m_2 = -\frac{1}{m}[/tex]
Substitute [tex]m = \frac{y_2 - y_1}{0}[/tex]
[tex]m_2 = -\frac{1}{(y_2 - y_1)/0}[/tex]
This gives
[tex]m_2 = -\frac{1\times 0}{y_2 - y_1}[/tex]
[tex]m_2 = -\frac{0}{y_2 - y_1}[/tex]
[tex]m_2 = -0[/tex]
[tex]m_2 = 0[/tex]
The slope of the line perpendicular to [tex]x = 8[/tex] is 0.

What is the domain and range of the graph below in interval notation? If union is needed, use Capital U. If infinity is needed use inf or -inf Format like this: D: (0,1000) R: (-inf,1000) **note the spaces after and after domain, but no spaces inside intervals.
Answer:
DOMAIN: [tex](-\infty,1]\cup(2,\infty)[/tex]
RANGE: [tex](-\infty,\infty)[/tex]
Step-by-step explanation:
The domain of a graph is the span of x-values covered by the graph, while the range of a graph is the span of y-values covered by the graph.
DOMAIN:
From the graph, we can see that the x-values covers everything to the left of x=1. Then we stop and then continue beginning at x=2 all the way until positive infinity.
However, note that at x=1, the dot is a closed circle while at x=2, the dot is an open circle. Thus, we will include x=1 into our domain but not include x=2 into our domain.
So, our domain is all values greater than or less than 1, and all values greater than 2.
In interval notation, this is:
[tex](-\infty,1]\cup(2,\infty)[/tex]
We use brackets with the 1 because we include it in our domain and we use parentheses with the 2 since we do not.
RANGE:
Looking at the graph, it seems that all y-values are covered. The part of the graph on the left covers all y-values less than or equal to 3, while the part of the graph on the right covers all y-values greater than -1. Thus, all y-values are covered.
Our range is all real numbers.
In interval notation, this is:
[tex](-\infty,\infty)[/tex]

Given m∠JML = 80 and m∠KML = 33, what is m∠JMK
Answer:
47°Step-by-step explanation:
Given m∠JML = 80 and m∠KML = 33, to calculate the value of angle m∠JMK, we will apply the formula since all the angles are all acting at point M.
m∠JML = m∠JMK+m∠KML
Substituting the values given into the equation;
80 = m∠JMK + 33
subtract 33 from both sides of the equation
m∠JMK = 80-33
m∠JMK = 47°
Hence the value of angle m∠JMK is 47°
Adam would like to build a deck thatbis 60,feet long by 8 feet hiw much wood would he need
Answer:
136 ft of woods
Step-by-step explanation:
1. Let us assume that we are solving for the frame of the deck alone
2. And also from the given parameters the deck has a rectangular shape
we know that the total amount of woods to be used is same as the perimeter of the rectangle.
Given that

A veterinarian is visited by many pets and their owners each day. Before the doctor attends to each pet, an assistant
records information including the type, age, weight, and height of each pet. Which of the variables is a categorical
variable?
The correct answer is Type
Explanation:
Categorical variables differ from other types of variables because these involve categories or defined groups. For example, sex is a categorical variable because in a population individuals are either classified as females or males (categories). This concept applies to types of pets because this variable involves categories or defined groups such as dogs, cats, hamsters, turtles, etc. Also, other variables such as age, weight, or height are not naturally categorical because these can be understood using numbers rather than categories.
Answer: The answer is definitely TYPE
Step-by-step explanation: For example the brand of a car is a category. You could have a Toyota. Toyota is a category of a car. Therefore, this can be applied in this problem; the Type of a pet is a category. The pet could be a dog or a cat e.t.c.
